NFS MW 2012 isn't running fullscreen in 1280x800

What I've done and it didn't helped:

1. Changed ScreenScale=3 parameter in config file

2. Changed Scaling=3 in all folders under: Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\GraphicsDrivers\Configuration\

3. Changed Windows resolution to 1280x800

4. Pressed Alt+Enter

5. Installed latest Intel Iris video driver

6. Changed NFS shortcut's run properties to "Maximized" and run it as administrator

7. Ticked this checkbox in driver's settings: http://prntscr.com/m5ueph

8. Re-installed the game on SSD bootcamp drive (C🙂

Please notice that the "Fullscreen" button is shown disabled: http://prntscr.com/m5u63o

Moreover, the game run in fullscreen only in native 2560x1600, but the game isn't playable due to lack of horsepower. 

I am running Windows 10 x64 on my Macbook Pro 2015.
